2. The stiffness of a close coiled helical spring is such that it deflects 36 mm when an axial load of 10N is applied on the end hook. Calculate (i) the mass to be hung on the spring so that when set vibrating it will make one complete oscillation per second. The mass of the spring is 0.6 kg. Calculate also the maximum velocity and the maximum acceleration of the vibrating mass when initially displaced 12 mm from equilibrium.
